CLINTON DQTABOR, OF SYRACUSE, NEW YORK, ASSIGNOR OF TWO-THIRDS TO THE SYRACUSE SASH AND DOOR COMPANY, OF SAME PLACE.

WINDOW-SCREEN FRAME.

SPECIFICATION forming part of Letters Patent No. 358,582,6lated March 1, 1887.

Application filed December 24, 1886. Serial No. 222,485. (No model.)

To all whom it may concern:

Be it known that I, CLINTON D. TABOR, of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in WindowScreen Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and I0 use the same.

My invention relates to an improvement in screens, and more particularly windowscreens.

The object is to provide a firm and unyielding frame for holding wire-gauze rigidly'in place, and for giving it a tight and even stretch throughout its entire surface.

A further object is to provide a simple and inexpensive frame of such construction that the wire-gauze might be readily removed or replaced with but little difficulty and without injury to the frame.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

111 the accompanying drawings, Figure l is a perspective view, showing the rear of my screen with a portion broken away. Fig. 2 is a view in elevation of the front of the frame. Fig. 3 is a view in cross-section of the screen. Fig. 4 is a View in edge elevation.

A A represent the sides of the frame, and A A the ends V-shaped on the outer edges. These sides and ends are of similar shape, and ordinarily the sides are somewhat longer than the ends, though this is by no means necessary.

Various designs for finishing the frame may be employed, and I find that the one shown in the drawings is very desirable, presenting a neat appearance and economizing material.

The frame is mortised together in a peculiar manner. One end of each side A A and 4.5 of each end A A is cut into the form of a lateral tenon, or, preferably \Ishaped on one side and slightly rounded on the opposite side, while the opposite end of each side A A and of each end A A terminates in a mortise, a,

of a shape corresponding to the tenon described.

It will be observed that from the formation of the mortise and tenon the tenoned end of each side and end of the frame must be entered in its respective mortise by a longitudi- 5 I nal movement of said side or end, and the mortised end of said side or end engages its respective tenon by a lateral movement. By this arrangement of mortise and tenon the parts are locked together against displacewent, the mortise on the ends A A of the frame in each case receiving a tenon on the sides A A of the frame, and the mortise on the sides A A receiving a tenon on the ends A A The formation described gives the frame firm and unyielding joints, and a single, pin through each joint is ordinarily sufficient to hold the frame rigidly together.

A V-shaped groove, 0, extends entirely around the inner portion of the frame on its rear, face. Wire-gauze D is stretched. across the frame toa point preferably on a line with the outer boundaries of the V-shaped groove 0, and for convenience in securing it in place it is tacked onto the frame at intervals. Securing-strips C, beveled at the adjacent ends, and of a formation on one face to correspond with the groove 0, are placed dver the wiregauze in the groove 0. The strips C are then nailed or secured firmly in place, thus tightly 8o drawing the wire screen and tightening the entire sheet of wire-gauze D, and bringing the outer face of the securing-strips flush with the rear face of the frame.

'It is evident that slight changes might be resorted to in the parts described without departing from the spirit and scope of my in vention; hence I do not wish to limit myself strictly ,to the exact construct-ion herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Awindowscreen frame consisting of the sides and ends, each of which is provided at one end with a tenon and at the opposite end with a mortise, the said tenons and mortises being shaped substantially as described, Whereby the parts of the frame are looked against longitudinal or lateral displacement, substantially as set forth.

2. A window-screen consisting of side and 5 end pieces jointed together and having a continuous groove in one face thereof, a wire fabrio the edges of which extend over the groove and are secured to the frame, and the securing-strips for forcing the wire fabric down into the groove and stretching the sanie, substan- 1o tially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
